Computer Science vs. Cyber Security Master's Degrees [What's the Difference?]
All cyber security professionals are computer scientists, but not all computer scientists work in cyber security.
Students in both degree tracks need excellent problem-solving skills and fluency in multiple programming languages. Both programs lead to high-paying jobs in a market where talent is scarce. Organizations struggle to fill computer science roles, and those who find work are frequently unprepared to tackle even basic security risks, according to the Harvard Business Review.
There are distinctions as well. For example, cyber security is just one computer science specialization—meaning it can be offered as a concentration in Master of Science in Computer Science programs, as well as an individual degree.
Both tracks are excellent, but which should you pick? Those who like investigating data breaches, identifying malware, and improving network security usually choose cyber security. In contrast, those who want to develop software or maintain databases pursue a general computer science degree or a different specialization. But, because these two paths are so interconnected, you don't necessarily need to pick one.
Computer science vs. cyber security: curriculum
Similar degrees can have different focuses, and looking at degree titles can be revealing. For instance, within the cyber security designation, you can earn a Master of Science in:
Applied Information Technology with a cyber security concentration
Computer Information Systems & Cyber Security
Computer Science with a cyber security concentration
Cyber Security Engineering
Overview of a typical master's in computer science curriculum
Computer science curricula can vary widely between schools, but there is lots of common ground—including among online programs. A typical master's in computer science curriculum covers:
Enterprise software design
Mobile systems and applications
Programs that accept non-computer scientists also cover such bachelor's-degree-level subjects as basic computer programming and data analysis. Alternatively, students may self-study equivalent undergraduate coursework, or complete a bridge program.
Overview of a typical master's in cyber security curriculum
Computer science programs offer cyber security classes, but obviously, a master's in cyber security goes deeper. Typical master's in cyber security degree coursework includes:
Cyber security architecture
Digital forensics/computer forensics
Information security strategy and policy
Additionally, while there are bachelor's degrees in cyber security, applicants commonly have a general computer science background.
Computer science vs. cyber security: specializations
Cyber security is far from the only computer science specialization. Top specializations and schools that offer them include:
This specialization prioritizes machine learning and other AI strategies. Southern Methodist University offers an AI specialization as part of its online computer science master's.
Computer engineering is a distinct discipline from computer science, though it shares common traits. Computer engineers focus more (though not entirely) on hardware than software.
Like most specializations, cyber security can be offered as a separate degree, or as part of a computer science program.
This specialization orients students to the relationship between people and technology; you'll learn data science as well as communication skills.
Distributed systems (aka distributed computing) is essentially an attempt to connect the disparate areas of a system. It has numerous practical and theoretical applications, and is usually offered as a research field.
Graphics and visualization
A graphics and visualization track covers subjects like:
Terrain modeling and rendering
Visual perception and spatial cognition
Mobile application development
Most mobile app developers are specialists because they focus on making software work across different platforms. You may not need a degree to pursue mobile app development.
Computer network architects are responsible for creating and maintaining entire networks—other positions in the field take on specialized roles. It's possible to pursue network architecture with a traditional computer science degree.
Operating systems education is a common part of cyber security coursework. There are jobs available for protecting, managing, and designing operating systems.
Traditional CS programs can prepare students for software engineering careers, but some schools have dedicated master's programs. Students take software engineering, data analysis, and artificial intelligence courses.
Computer science vs. cyber security: job outlook
According to the United States Bureau of Labor Statistics (BLS), the computer and information technology field is expected to grow by 11 percent from 2019 to 2029—more than triple the rate for the job market as a whole. This figure encompasses all computer science careers, including cyber security. Like the others in this section, this number is a good starting point, but individual jobs still grow at different rates.
Computer science job outlook
The BLS expects computer and information research scientist employment to grow by 15 percent from 2019 to 2029.
Cyber security job outlook
The BLS projects information security analyst employment to grow by a staggering 31 percent from 2019 to 2029.
Computer science vs. cyber security: career paths and earning potential
Examining job outlook numbers is an excellent way to identify trends, but looking at career paths provides a more detailed picture. These are some top jobs you can get with a master's degree.
PayScale says the average salary for someone with a master's in computer science is $102,637. The best jobs pay considerably more. Likewise, the average salary for someone with a master's in cyber security is nearly $87,000—and, again, top positions pay more.
Career paths aren't rigid in computer science. Just because a degree is popular, it's not the only relevant one. A strong business background may be enough for specific computer science jobs—others may not require a graduate degree at all.
The best jobs you can earn with a master's in cyber security or computer science, and their average annual income, include:
Chief information security officer ($165,000): You can perform this job with either degree or even a Master of Business Administration (MBA).

Master's in computer science vs. master's in cyber security: which is for you?
Ultimately, you can't go wrong with either degree, assuming you have technical skills and enjoy working with computers.
A master's in computer science is worth it on the condition that you have the time and resources to dedicate to a program—this rule applies to graduate programs in any discipline. While master's in computer science programs exist for professionals at every level, those who use their degrees to advance or develop specific expertise often benefit the most. Even though professionals with a master's in cyber security earn less, on average, than their computer science counterparts, they usually have a more focused skill set.
Bottom line? You can't go wrong with either degree.
